I just noticed that, when seeking power, the tendency is to turbocharge. This left me to wonder, why not supercharge? It's easier and ussually cheaper to install a centrifugal supercharger than to install a turbo, but I've never come across a supercharged Civic. Is there any particular reason behind this, besides the inherent loss of efficiency with a supercharger over a turbo? Or is it the hood space? It seems that could be overcome with simple modification. So, what is it?
